Summary
This earth dam, with a height of 18 feet and a length of 625 feet, controls the flow of the West Fork Lewis Creek and creates a surface area of 17.9 acres. Despite its impressive storage capacity of 211 acre-feet, the dam poses a high hazard potential due to its unsatisfactory condition as of the last assessment in January 2020.
With a drainage area of 0.23 square miles, the Winona Country Club Lake Dam has a spillway type classified as uncontrolled, highlighting the need for regular inspections and maintenance to ensure public safety. The dam's Emergency Action Plan was last revised in December 2018, and its risk assessment indicates a moderate level of risk. The associated risk management measures and inundation maps for the dam remain pending, leaving room for improvement in emergency preparedness and response.
Despite its condition and hazard potential, the Winona Country Club Lake Dam continues to serve as a vital recreational resource for the community. As water resource and climate enthusiasts, it is important to monitor the dam's maintenance and regulatory compliance to safeguard both its structural integrity and the surrounding environment. By staying informed and advocating for sustainable dam management practices, we can contribute to the long-term resilience of this essential infrastructure.

Dam Data Reference
Condition Assessment
SatisfactoryNo existing or potential dam safety deficiencies are recognized. Acceptable performance is expected under all loading conditions (static, hydrologic, seismic) in accordance with the minimum applicable state or federal regulatory criteria or tolerable risk guidelines.
Fair
No existing dam safety deficiencies are recognized for normal operating conditions. Rare or extreme hydrologic and/or seismic events may result in a dam safety deficiency. Risk may be in the range to take further action. Note: Rare or extreme event is defined by the regulatory agency based on their minimum
Poor A dam safety deficiency is recognized for normal operating conditions which may realistically occur. Remedial action is necessary. POOR may also be used when uncertainties exist as to critical analysis parameters which identify a potential dam safety deficiency. Investigations and studies are necessary.
Unsatisfactory
A dam safety deficiency is recognized that requires immediate or emergency remedial action for problem resolution.
Not Rated
The dam has not been inspected, is not under state or federal jurisdiction, or has been inspected but, for whatever reason, has not been rated.
Not Available
Dams for which the condition assessment is restricted to approved government users.
Hazard Potential Classification
HighDams assigned the high hazard potential classification are those where failure or mis-operation will probably cause loss of human life.
Significant
Dams assigned the significant hazard potential classification are those dams where failure or mis-operation results in no probable loss of human life but can cause economic loss, environment damage, disruption of lifeline facilities, or impact other concerns. Significant hazard potential classification dams are often located in predominantly rural or agricultural areas but could be in areas with population and significant infrastructure.
Low
Dams assigned the low hazard potential classification are those where failure or mis-operation results in no probable loss of human life and low economic and/or environmental losses. Losses are principally limited to the owner's property.
Undetermined
Dams for which a downstream hazard potential has not been designated or is not provided.
Not Available
Dams for which the downstream hazard potential is restricted to approved government users.
